If you’ve spent any time on social media lately, you’ve probably seen videos of people dropping a dishwasher tablet into an empty washing machine and running a hot cycle. Many claim it removes hidden grime, eliminates odors, and leaves the drum sparkling clean.
It sounds like an easy cleaning shortcut—but is it actually a good idea?
Here’s what happens when you use a dishwasher tablet in a washing machine, along with what appliance experts generally recommend instead.
Why Do People Use Dishwasher Tablets?
Dishwasher tablets are designed to break down grease, food residue, and mineral deposits inside a dishwasher.
Because they contain powerful cleaning agents, many people assume they’ll also remove detergent buildup and residue inside a washing machine.
Some users report that the drum looks cleaner after trying the hack.
Does It Actually Clean the Washer?
A dishwasher tablet may dissolve some residue inside the drum during a hot wash cycle.
However, washing machines and dishwashers are built differently and use different types of detergents and cleaning products.
A cleaner designed for one appliance isn’t necessarily intended for another.
Could It Damage the Washing Machine?
Possibly.
Some washing machine manufacturers advise against using dishwasher tablets because their ingredients aren’t formulated for washing machine components.
Over time, repeated use could contribute to:
- Excessive suds
- Residue buildup
- Wear on seals or internal parts
- Potential warranty issues if used against manufacturer recommendations
Always check your owner’s manual before trying any cleaning hack.
The Best Way to Clean a Washing Machine
Most manufacturers recommend cleaning your washer using one of the following:
- A washing machine cleaner specifically designed for your appliance
- The machine’s built-in cleaning cycle (if available)
- Cleaning products approved by the manufacturer
Many newer washers include a Tub Clean, Drum Clean, or Self Clean cycle.
Running that cycle regularly helps remove detergent residue and odors.
How Often Should You Clean Your Washer?
For most households:
- Clean the washing machine about once a month.
- Leave the door open after each load to allow the drum to dry.
- Wipe the rubber door seal regularly.
- Clean the detergent and fabric softener dispensers.
- Remove lint or debris from the drain filter if your model has one.
Regular maintenance helps reduce mold and unpleasant smells.
What Causes Washing Machine Odors?
Bad smells often develop because of:
- Detergent residue
- Fabric softener buildup
- Mold or mildew
- Standing water
- Poor ventilation
Front-loading washers are especially prone to moisture collecting around the door gasket.
Better Ways to Keep Your Washer Fresh
Simple habits can help prevent odors before they start:
- Use only the recommended amount of detergent.
- Remove wet clothes promptly.
- Leave the washer door slightly open after each load.
- Wipe the door gasket dry.
- Run the recommended cleaning cycle regularly.
These small steps can make a noticeable difference.

Final Thoughts
Using a dishwasher tablet to clean a washing machine has become a popular internet hack, and some people report good results. However, because dishwasher detergents aren’t designed for washing machines, it’s generally safer to follow your appliance manufacturer’s cleaning recommendations.
A monthly cleaning cycle, proper detergent use, and a little routine maintenance can help keep your washing machine fresh, clean, and performing its best for years to come.
